RECEPTACLE ESPECIALLY ADAPTED FOR MUSTARD.

Specification of Letters Patent.

Patented May 25, 1909.

Application led February 27, 1907. Serial No. 359,704.

T o all 'whom it may concern.'

Be it known lthat we, `CARL FlnEDRlcn WILHELM LINDEWIRTH and EUGENARTHUR WIECK, residing at Bielefeld, NVcstphalia, Kingdom of Prussia,German Empire, subjects of the German Emperor, haveI invented new anduseful Improvements Relating to Receptacles Es ecially Adapted forMustard, of which the fo lowing is a specification.

It is a Well known fact that mustard is exposed to decomposition by theVaction of light and air, and particularly of the air, whereby the use ofthe mustard may be rendered extremely prejudicial to health, while itsliavor is likewise detrimentally affected. Means heretofore provided forimprovingv these conditions are ineffective and are likewise mostlyobjectionable from the hygienic point of view. In all known devices, theexclusion of air is incom lete, and the mani yulation is not cleanly.wing to the insuflic1ent exclusion of the air, the receptacles inwhichthc material isl stored, or from which it is taken .for use formfavorable places for the deposit of bacteria, and this is articularly soin places of ublic resort. his of course hastens the ecomposition of themustard, and the use of such mustard may be highly prejudicial tohealth. The uncleanly manipulation consists in the use of spoons foremptying the receptacles, these spoons mostly consisting of a materialwhich is attackable by the acids contained in the mustard, thusrendering the latter harmful to health, especially as they arefrequently allowed'to remain in the receptacle.A In course of time theappliance used for taking the mustard will be almost entirelydecomposed. In addition to this, in all businesses in which mustard isused or sold the hard upper layer of the mustard which, owing toexposure to the air in the receptacle becomes decomposed and assumes adark brown color, is commonly stirred up with the rest of the mustardcontained in the receptacle, as in large businesses its removal wouldentail a large monetary loss. Accordingly for reasons of economy thelaws of health are disregarded. /v

' 'lhe present invention obviates these defects completely. The mustardis protected in the receptacle from the action of air and light. j It iswithdrawn in a cleanly manner for use and in accordance with theinvention it is unnecessary toopen the receptacle or `the spindle a torotatewith it.-

employ special spoons or the like. The'mustard always remains fresh tothe last drop,

and will keep for almost an unlimited ti1ne This is of especialimportance for export and use on ships or during long journeys.

In accordance with the invention, by actuating a train of gearingsimultaneously with the descent oll the pressure piston or plunger,that'is to say the emptying of the receptacle by displacing theoperating handle, the discharge valve is automatically opened, and onreleasing the handle and stoppmg the descent Figure 1 shows itinvertical section, Fig. 2 is a section on the line A of Fig. 6 showingthe connecting rod for the lever which is connected with the spindle towhich the handle is fitted. Fig. 3 is a front elevation of the forkconnecting the handle-s indle with the said connecting rod. Fig. 4sliows the upper part of the receptacle viewed in the directionindicated by the arrow l in Fig. 1, on a larger scale and partly insection. sents a horizontal section through the operating gear on anenlarged scale. Fig. '6 is a top view of the receptacle, and Figs. 7 and8 illustrate the hub of the handle in side elevation and in plan on alarger scale.

In the constructional form of the devicel here illustrated the bottomend/a3 of the re- Fig. 5 repreceptacle a is provided at its middleportion with a cavity 'a4 in which the hollow spindle a is guided.A Thelid nl is attached to the rece tacle n by means of a bayonet joint, pinso fixed on the receptacle lL-entering angular slots o1 in the lid n1.discharge tube d and the ho low spindle a are mounted in the neck ns ofthe lid. v The prolonged hub portion b1 of the worm wheel b is formedinternally as a hexagon at its lower part; the hexagonal head a1 of thespindle a -is inserted in this hexagonal recess'so that when the wormWheel b is rotated it causes The'surface The o erating gear, the

of the spindle a is ehamfered slightly inward mounted'in the worm 1], e

spindle for the in order to provide a tight joint for the stationarydischarge tube d which is likewise correspondingly chamfered. The casing1n is fitted to the neck a5 of the lid; it is closed by a lid p andserves for the reception of the worm gear and for the mounting of thewormf. In the neck p1 of the lid p a screw thread is formed into whichthe correspondingly threaded discharge tube d is screwed. A counter nutg enables the discharge tube d to be tightened or loosened for thepurpose of estab ishing a good joint between it and the spindle a.

The spindle e for the handle is displaceabljT the square 'portion e1(Fig. 5) of the spind insurlng the driving of the worm f when the handleh is rotated. In the cavity m3 of the hub of the worm f, which is closedon one hand by the collar r and on the otherbyan annular part r, aspring m is located for returning the handle to its position of repose;it bears against the collar rFig. 5. The handle h is fixed to therolonged hub of the worm f. On the hub L of the handle ZL inclinedsurfaces i, 'il are provided which when the handle h is turned pressforward the pin g sliding upon them and which is fixed'on the spindle e,thereby displacing the latter. The hub h1 of the handle is covered by a.cap efixed on the handle h at h2; one end of the -spiral s ring s1 isfixed to this cap while its other en surrounds 'the pin g. The specialobject of this spring is to assist the rotation of the-handle whenthelatter is returning to its position of re ose.

Above the lid p a rod 7c is mounte in the same direction as the spindlee and is likewise subjected to the action of a spring m1. The rodI 7crests in bearin s z z2 which are cast upon the lid p. A for tis fixed tothe rod k,

.l rod k is likewise displaced in the same direction owing to theconnection of the two parts l by' means of the fork t. On the end of therod Zc opposite'to the fork t an arm v carrying a pin' v is xed. Thispin engages in 'the longitudinal. slot 'w' in the arm 'w which ismounted on the rod c-'whichrests in bearin s x, z fixed to the lid p atan angle Ato the rod This rod also `carries an arm Z provided. with launiversal joint y. In this joint there eniges va lever'lzwhich isjointed to the arm Z3 ed tothe valve body d3.

A sprlng n is soldered-to the lid ni at z and -presses on-'the-piston cin the raised position of the latter in order to insure the engagementof the screw threads on the piston and urpose o f depressing thep1ston.-.To faci tate the manipulation of the piston c it is providedwith a collar c3 which is preferably screw-threaded to' enable the istonto be inserted and withdrawn readl y. The tapering annularspace c*inside lthe screw threaded hub of the piston c has for its object topermit of the discharge of the contents of the receptacle through theopenings a3 provided in the lower part of the spindle (L even in thelowest position of the piston. Between the piston ring c2 and theleather sleeve c an annular space c5 tapering upward is left free; thematerial is forced into this space upon the depression of the piston. Bythis means a good joint is formed between the sleeve c and the innerwall of the receptacle n and considerable friction is produced betweenthese parts for the vpurpose Voi' preventing rotation-ol' thev piston cwith the spindle a. The leather sleeve c is fixed on the piston ringcgby an annular part c by means of screws c7. All the parts of thereceptacle and of the discharging device which come into contact withthe. contents are formed of acid prooi' material, such as ebonite,porcelain or the like.

The valve casing d2 intersects the valve body d3 at the outlet in orderto prevent dripping after the valve d vhas been closed. Any dropsremaining pendent are carried inward when the valve body d rotates, orare cut oil' by it so that they fall into the vessel placed below forthe reception of theinustard.

The operation of the apparatus is as 'follows :s-After lthe receptacle'n has been charged, the spindle e 1s iirst of all inserted so that itrests in the cavity n* in the bottomn3 of the receptacle. The piston cis then loosely mounted on the spindle a. and the'lid 'n' is closed. Bythe action of the spring-1n2 on the piston c, when the handle h isrotated the screw thread on the piston is caused to mesh with the threadof the hollow spindle a. At the same time, owing to the-pin g strikingagainst the inclined surfaces t, '1, on the hub h of' the handle, thespindle ef is displaced. By means of the fork t they rod Ic is displacedin the same direction whereby the springs m, fnt, s are compressed.v Therod Zc, by means 'w aside, whereby the ro cis rotated Jand the. arm Z ofthis rod lifted. By this means th lever Z2 is pressed upward and thevalve body d3 is rotated-by the arm Z3 which is jointed to the lever Z2,that is to'say, the discharge valve d is opened. By the further rotationof the handle the piston -c'is depressed whereby the material'with whichthe receptacle is'charged is caused to escape through the o enings ainthe hollow spindle a out of the atter i'nto the discharge tube d andthence through the .of the arm 'v' and pin "v" resses the lever arm usedequally well for, appliances from which the material is taken for use orreceptacles in which it is stored, may of course be modified in variousWays.

By means oi' the arrangement described, it is possible as soon as areceptacle is emp'- tied to remove the lid readily and fit it to afreshly filled receptacle and thus toa certain extentan operative systemis provided.
